Simon Greener: "A lot of work went in to designing our application database. PHP Generator allowed us to build a fully functional, professional looking, and functionally powerful web application from that database. It has freed us from worrying about low level code, enabling us to focus on the business requirements of the customer. The support provided is excellent with staff quickly producing answers to questions ranging from newbie to simple or complex. I highly recommend the product".
John Gondek: "Your software is amazing. I consider myself a novice at PHP and JS and with your software I have a web page that is truly fantastic. Thank you so much ".

OnPageLoaded

This event occurs after the page is completely loaded from the server. It allows you, for example, to add additional filters to the dataset.

 

Signature:

function OnPageLoaded()

 

Parameters:

This method has no parameters.

 

Example 1

The following code is used in our Schema Browser Demo to filter database objects belonging to the selected database:

 

applyDatasetFilter($this->dataset);

 

Here applyDatasetFilter() is a function defined in the schema_browser_utils.php file as follows:

 

function applyDatasetFilter(Dataset $dataset) {

    if (GetApplication()->IsGETValueSet('database'))

        $value = GetApplication()->GetGETValue('database');

    else

        $value = ArrayUtils::GetArrayValueDef($_COOKIE, 'database');

    if (StringUtils::IsNullOrEmpty($value)) {

        $globalConnectionOptions = GetGlobalConnectionOptions();

        $value = $globalConnectionOptions['database'];

    }

    if (!StringUtils::IsNullOrEmpty($value)) {

        $dataset->AddFieldFilter('Database_name', new FieldFilter($value, '='));

        setcookie('database', $value);

    }

}

 

Example 2

The following code is used to filter countries by life expectancy:

 

// default values

$minLifeExpectancy = 40;

$maxLifeExpectancy = 90;

 

// checking values in the browser address line 

if (GetApplication()->isGetValueSet('minLifeExpectancy') &&

       GetApplication()->isGetValueSet('maxLifeExpectancy')) {

    $minLifeExpectancy = GetApplication()->GetGETValue('minLifeExpectancy');

    $maxLifeExpectancy = GetApplication()->GetGETValue('maxLifeExpectancy');

 

}  // or (if not found) in the session

elseif (GetApplication()->IsSessionVariableSet('minLifeExpectancy') && 

          GetApplication()->IsSessionVariableSet('maxLifeExpectancy')) {

    $minLifeExpectancy = GetApplication()->GetSessionVariable('minLifeExpectancy');

    $maxLifeExpectancy = GetApplication()->GetSessionVariable('maxLifeExpectancy');

}

 

// applying filter to the dataset

$this->dataset->AddCustomCondition(

    "life_expectancy >= {$minLifeExpectancy} ".

    "AND life_expectancy <= {$maxLifeExpectancy}");

 

// saving calculated values to the session

GetApplication()->SetSessionVariable('minLifeExpectancy', $minLifeExpectancy);

GetApplication()->SetSessionVariable('maxLifeExpectancy', $maxLifeExpectancy);
